10. Proper Welding Techniques – Drader Injectiweld – Butt Welds
Butt Welds
Correct Alignment
Welding tip is in
correct alignment
o
when it is at a 90
angle
Welding tip is in
correct alignment
when it can reach the
root of the other side
of the parent plastic
Welding tip is in
correct alignment
when its edges
contact each side of
the parent plastic
material
Welding tip is in
correct alignment
when molten welding
rod penetrates the
root of the parent
plastic material
If welding from one
side, welding rod
must fill the root of
the parent plastic
material
If you can weld from
both sides, make two
o
90 bevels before
welding
Butt Welds
Incorrect Alignment
Welding tip is
not in correct
alignment when it is
o
not at a 90 angle
Welding tip is
not in correct position
when its melting
surface does not
contact the plastic
Welding tip is
not in correct position
when its melting
surface does not
contact the plastic
Welding tip is not in
correct alignment if
molten welding rod
cannot penetrate the
root
A poor weld because
molten welding rod
did not penetrate the
root.
Lack of penetration
will result in a poor
butt weld
